' It is an object of my inventionto provide a packing machine formeat loaves and such like meat products which will be inexpensive to construct and which will be easy and positive in operation. In the past it has been found necessary topack meat loaves and the like bykneadingwith the hands inorder to eliminate the air spaces and reduce the prod- .uct' to a compactand shaped form as well as to. thoroughly mix the ingredients.

It is a further object of my device; to

not in any way with the hands for'the purpose of either eliminating these air spaces or formixing the ingredients. Thisis entirely accomplished by my device automatically.

I 'A further object ofmv. device isto meet the requirements of the United States Government food inspectors in thatthe product is not'manip-ulated by hand wherever possible. My'inventionl will be more readily understood by reference to the accompanying drawings in which like numbers refer to like'parts.

. i i Fig. 1 is a partial side elevation and partial sectional view showing the pan receiv .ing a charge of meatproduct. Fig. 2 isi-a 1 sectional view similar to Fig.1 with the parts shown in'po'sition after. the pan has been filled and ready for removal." Fig. 3

I isla sectional view taken: on the plane 3-43 ,of Fig. 1. Fig. 4 is aplan section taken on I e which a pan 20 is passed between the guides 19and placed upon-the'beveled edges 21 ofa the plane 4- 4 of Fig. 1. Fig. is an inverted plan view looking in the direction of the arrow 5 of Fig. 1.

- By reference toFi'g. 1 it will be'seen that the machine consists mainly of a body portion 10 having sidewalls 12, a base 14 and oughly mixes the product..',The handle 50 a top 16. There is an opening 18 in the front, wall (thewall facing the operator and into which the pan is inserted).- through pair of slidable blocks 22. The blocks slide on the base 14 and between the walls 122's shown in Fig. locking collar 24 conn'ectsa neck 26 of a feedspout- 28 to. the meat;

'The 'saidshanks 62 also pass through elongated slots'64 in the base 14. The other end of each of these links 58 and 60 issecured at ofthe knife plates 36 and '38 for a purpose to beherein'after described; The operation of the device is as follows:

iThe pan 20 is passed through the opening -18: between the guides 19 and placed'on the beveled edges 21 of blocks 22" directly under :spout 28.

The pressure behind the meat in the spout 28 forces same into the pan 20 as shown in Fig.1 and'removes'all air spaces and thoris now pulled tothe right whichcloses the knife plates. wh ch in closing forma mound shape or loaf "shape portion abovethe pan T due to the curved shape of the knife plates and theaction of the 'rubberflaps 7 6.
